Chicago Aldermen approved a change to the STR rules Wednesday that altered the trajectory of two lawsuits challenging the home-sharing ordinance. Under the change, city inspectors would need a search warrant or subpoena to access the lists of guest information that hosts must keep.

After the City Council's tweaks, a judge in one of the suits extended a delay on implementing parts of the ordinance from Tuesday to Friday.

The extension gives Keep Chicago Livable, the lead plaintiff in the case in which the judge ruled Thursday, time to file an amended complaint, said Shorge Sato, an attorney for the nonprofit. The judge could extend the delay still further if the city needs more time to respond.

"The changes that (the city) made were an attempt to address some of the, I think, more flagrantly unconstitutional parts of the law, but they left a lot still out there," Sato said.

The suing group's objective remains the same: to have the law removed, let the "sharing economy" govern itself and "let the people of Chicago use their homes as they see fit," Wolf said.
